When Randy Moss works out for the San Francisco 49ers on Monday, coach Jim Harbaugh will be the guy throwing Moss passes.

Harbaugh, a former NFL quarterback, will take his throwing arm out of hibernation for Moss’ audition. No current 49ers quarterbacks are allowed to throw for a workout until the league year begins Tuesday. So Harbaugh is answering the call, which will make Moss’ workout even more interesting.
